Every season on the Real Housewives, the ladies’ friendships go through the wringer.

With E! News reporting that “Real Housewives of Beverly Hills” star Brandi Glanville and pal Lisa Vanderpump’s friendship was on the rocks, it was only a matter of time before a new “odd couple” was formed.

That said, we thought pigs would fly before Brandi and Kyle Richards formed an unholy alliance. The drama reportedly began when the Housewives hit Puerto Rico to film for the new season.

According to Radar, Lisa and Kyle are on the outs following an argument on the trip over tabloid rumors that Kyle’s husband, Mauricio Umansky, had been unfaithful.

The British beauty was called out for being “a back-stabbing friend,” which in turn lead Kyle and Brandi to join forces.

“[They] have become a lot closer after the Puerto Rico incident,” a source tells Radar. “The two have been spending time together.”
